It is a shame that Congress doesn't study Supreme Court cases, and those who oppose legislation like this do not invoke previous High Court rulings:
"A law repugnant to the Constitution is void. An act of Congress repugnant to the Constitution cannot become a law. The Constitution supersedes all other laws and the individual's rights shall be liberally enforced in favor of him, the clearly intended and expressly designated beneficiary."
~ Marbury v. Madison, (1803)
"Where rights secured by the Constitution are involved, there can be no rulemaking or legislation which would abrogate them."
~ Miranda v. Arizona (1966)
"An unconstitutional act is not a law; it confers no rights; it imposes no duties; it affords no protection; it creates no office; it is in legal contemplation as inoperative as though it had never been passed".
~ Norton v. Shelby County, Tennessee (1886)
